Resolva as equações em R. 1) 2 x + 6 = x + 18
2) 5 x – 3 = 2 x + 9
3) 3 (2x-3) + 2 (x + 1) = 3x + 18
4) 2x + 3 (x – 5) = 4x + 9
5) 2 (x + 1) – 3 (2x –5) = 6x – 3
6) 3x – 5 = x – 2
7) 3x – 5 = 13
8) 3x + 5 = 2
9) x – (2x – 1) = 23
10) 2x – (x – 1) = 5 – (x – 3)
2) 5 x – 3 = 2 x + 9
3) 3 (2x-3) + 2 (x + 1) = 3x + 18
4) 2x + 3 (x – 5) = 4x + 9
5) 2 (x + 1) – 3 (2x –5) = 6x – 3
6) 3x – 5 = x – 2
7) 3x – 5 = 13
8) 3x + 5 = 2
9) x – (2x – 1) = 23
10) 2x – (x – 1) = 5 – (x – 3)
